Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 54-21-7, Name is Sodium salicylate, SMILES is OC1=CC=CC=C1C([O-])=O.[Na+], belongs to indole-building-block compound. In a document, author is Singh, Anoop, introduce the new discover, COA of Formula: C7H5NaO3.
Synthesis of C2-tetrasubstituted indolin-3-ones via Cu-catalyzed oxidative dimerization of 2-aryl indoles and cross-addition with indoles
An efficient protocol for the synthesis of 2,2-disubstituted indolin-3-ones under mild conditions has been developed. This reaction involves the copper-catalyzed in situ oxidative de-aromatization of 2-arylindoles to indol-3-one, followed by self-dimerization as well as cross-addition with indoles under mild conditions. The result generates a wide variety of C2-tetrasubstituted indolin-3-ones with good to high yields (62-82%).
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 54-21-7 is helpful to your research. COA of Formula: C7H5NaO3.
